Hi!
Not sure if I am a bit late to the party but I am also East Midlands based. I am looking to getting a Bengal and/or Savannah kitten and found a place over Grantham way call 'purebliss bengals'. I have had a quick look over this forum to see if there is are any recommendations for them, but not seen anything at all (although has been a very quick look over).
I went to visit them a few months ago and they were really nice, I met their adult cats and a litter of kittens and they they were all beautiful. It was feeding time and they were all being treated to chicks!
Having said all that, this is the only cattery I have visited so far, so nothing to compare it too!
